I did have a few problems getting it rooted the first time around, so here’s a few notes in case you get stuck as well.

“Now the shell should display “$” – your’s says “#”In this case, I was trying the steps based on a previous problem I had and didn’t reboot first. After rebooting the phone, I was able to proceed as directed in the instructions.

“Here you will rename the downgrade RUU as PG05IMG.zip and place it on your SD card. Then, run the following command:”
The first time around, I downloaded the wrong RUU. You need to download the RUU_Mecha_VERIZON_WWE_1.03.605.10_Radio_1.02.00.0103_2r_NV_8k_1.37_9k_1.52_release_165253_signed.zip, copy it to the root of your sdcard then rename it to PG05IMG.zip before flashing

“Push wpthis, busybox, and psnueter.”
I had problems getting adb working on this step. I forgot I had to turn USB Debugging back on because we just flashed a new RUU.
